I created this page to solve a problem: what to do when someone
invites me to dinner at their home. That's all a very nice thing, not
a problem -- the difficulty is that I have extensive (non-dangerous
but unpleasant) food allergies. (My condition is known as
eosinophilic esophagitis.)
So, there are multiple lists, which are likely to evolve as I continue to figure this out.
